I'm having trouble signing a transaction with two inputs on https://coinb.in. If I select the Sig Hash Type "All (default)" on the Sign tab and sign the transaction with the private key for one of the inputs, a signed transaction is generated. If I paste this into the raw transaction box and sign it again with the second private key, another signed transaction is generated. If I verify this transaction in the Verify tab, it shows the correct inputs and outputs and shows both the inputs as signed. However, when I go to broadcast the transaction, I get the message "TX decode failed". I've tried with all the different Sig Hash Types and I always get the same error. Any help would be much appreciated.
